摘要：

An easy-to-use phantom has been constructed for checking the accuracy of a stereotactic computed tomography localization system. This phantom has been used on a commercially available stereotactic radiosurgery system. With this system, the phantom reference point, whose location is established by means of a precision measuring implement, can be localized by a computed tomography (CT) scanner with a standard deviation of measurement that is less than 0.3 mm in three orthogonal axes.
